DataGrip stuck on “connecting to database…” while connecting to Redshift

I try to connect to Redshift Using JetBrain DataGrip, after I fill in the datasource information (host, db, username, password etc) and try Test Connection I saw that there is a background task spawn up and prompts "Connecting to database..." and stuck there forever.

I'm able to connect with SQL WorkbenchJ with same datasource information.

Has anyone encounter this issue?
